Oscar-winning actress was diagnosed with advanced macular degeneration in 2012 and has been dealing with the loss of her vision.While appearing on The Graham Norton Show, Dench admitted that she has found it harder and harder to read scripts and learn her lines.“It has become impossible and because I have a photographic memory I need to find a machine that not only teaches me my lines but also tells me where they appear on the page,” she said.“I used to find it very easy to learn lines and remember them,” she continued. “I could do the whole of ‘Twelfth Night’ right now.”In 2021 interview with The Guardian, Dench revealed that she asks her friends to help her with lines by reading them out loud to her.“You find a way of just getting about and getting over the things that you find very difficult,” she said at the time.
